A particular object of the invention is vto provide improved apparatus forhandling al internal diameter, but thefwall thereof is relatively thin, and when two or more spiral ipe. p Another particular object of the invention is to provide improved apparatus for welding tubular members to each other.

Still another particular `object of the invention is to provide improved apparatus for welding tubular end-pieces, flanges, or the like, to the ends of a previously formed pipe, or the equivalent. l, i

A preferred form of the invention is einbodied in apparatus for ,welding tubular endpieces of standard pipe dimensions to spiral pipe which has standard internal diameter, n

shown a spiral pipe at to which end-pieces but does not' have a wall of corresponding thickness. The 'apparatus comprises ini- .,proved meansl for supporting and rotating the pipe andthe standardend-pieces while theendpieces are being welded to the pipe.

Many other objects and advantages will become apparent as thisv description progresses, reference being had nto the accompanying drawings, wherein` Figure 1 is aside elevation of the apparatus lwhich embodies the invention;

Fig. 2 is an enlarged side elevation, partly in section, of a part of the apparatus shown "inF1g.1;

6 5 of- Fig. 4, a portion of the figure being broken away to "permit it to be shown in a relatively large scale, and

Fig. 7 is a centra-l section through a portion of the apparatus shown at the right-hand end of Fig. 1.y

In the drawings, have illustrated one form of the invention embodied in apparatus for welding end-pieces to spiral pipe which v has been 'previously formed by winding a Y strip or ribbon of lmetal into spirally related convolutions, the convolutions being joined to each other by any suitable means, such as a lock-"seam, a welded lock-seam, or a welded lap seam. Spiral pipe of this character is generally manufactured to have a standard pipe, the end-pieces being formed lwith standard internal and external diameters so that standard pipe screw-threads may 'be provided thereon, or so that the end-pieces of l `one pipe may be connected to the end-pieces of another pipe by standard cou ling devices.

Referring for the present to ig. 1 I have 11 and 12 are to be welded. The" pipe 10 is formed lof. a plurality of spiially related convolutions 13vjoined to each other by a seaml. In this instance, the-pipe V10 is assumed to have a'standard internal diameter, but the external diameter thereof is less than the corresponding standard external diameter for wrought iron pipe. The tubular end-pieces, 11 and 12 have internal and external diameters which are standard; and it i is readily understood that standard pipe screw-threads may be cut thereon,'or that a y plurality of the pipe with their ends may be coupled toeaeh other by standard coupling devices.

v As shown, the spiral pipe 10 and the tubular end-pieces 11 and 12 are supported by and between two truck units which are identified by reference characters 20 and 21. As hereinafter described, the truck units 2O and 21l may be brought into a plurality o f adjusted positions with respect to each other, and in this instance the truck unit 21 is preferably secured in a permanent position.. Thus, it will be noted that the truck unit 21 'is providedI with bracket members 23 in which setscrews 24 are provided for rigidly securing `or'locking the truck unit 21 to rails 26 upon which the two truck units are mounted. Ink

termediate the truck units 20 and 21, I have shown ways 28 and 29 upon which the spiral pipe may be rolled into a position wherein it is in alinement with the truck unit-s 20 and 21 so that the operators of the apparatus may readily load the pipe upon members adapted to-rotate it, while the ends are being welded thereto.

The construction of the truck unit 20 is illustrated in detail in Figs. 2 to 6, inclusive. It preferably comprises a frame which is designated generally by reference character 30, the frame being provided with suitable wheels 32 adapted to travel upon the rails 26. Mounted in the frame is an electric motor 34 which is operatively connected by a sprocket chain 35 `to a shaft 36 rotatably journaled in the frame, the shaft 36 being the main drive-shaft of the apparatus. Fixed to the shaft 36 is a sprocket 38 operatively connected by a sprocket chain 39 to a sprocket 40 fixed to a shaft 41 rotatably j ournaledk in the frame 30. (See Fig. 3.) A sprocket 43 journaled on the shaft 41 is connected by a sprocket chain 44 to a sprocket 45 rigidly secured to a shaft 46, also rotatably journaled in the frame 30. A pinion 47 rotatably journaled upon the shaft 41 meshes with a gear 48 secured to the shaft 46, suitable clutch mechanisms and 51 being mounted upon the shaft 41 to control the above described means connecting the shaft 41 to the shaft 46. Thus, the clutch mechanism 50 comprises a member 53 constrained to rotate with the sprocket 43, the clutch member 53 being frictionally engageable by a clutch member constrained to rotate with the shaft 41, and the clutch mechanism 51 comprises' a'member 56 constrained to rotate with the pinion 47 and frictionally engageable by a member 57 constrained to rotate with the shaft-41. A clutch collar 59 mounted upon the shaft 41 intermediate the clutch members 55 and 57 is operatively connected to these members and may be displaced to hold both of the members 55 and 57 simultaneously in position,

wherein they do not effectivelyengage the clutch members 53 and 56, respectively, or to hold either one of the clutch members 55 and 57 in effective engagement with its associated clutch members 53 or 56 while the other is disengaged. Means for displacing the clutch collar 59 preferably comprises a lever 60 having bifurcated ends 61 engaging pins 62 projecting from the collar 59, the lever being rigidly secured to a pin 64 p ivoted in the frame 30. Secured to the pin 64 is a lever or handle 66 which projects from the truck andmay be manipulated by the operator of the apparatus.

A sprocket 68 Xedly secured to the shaft 46 is connected by a sprocket chain 69 to a sprocket 70 fixed to a shaft 72 journaled in the frame 30 (see Fig. 5). A pinion 73 keyed to the shaft 72 meshes with a gear 74 rotatably journaled upon a shaft 75, the shaft 75 being journaled in the frame 30 and having two of the wheels 32 fixed thereto. Formed integral with the gear 74 is a pinion 76 free to rotate with respect to the shaft 75, the pinion 76 being arranged to mesh with a gear 78 rotatably journaled upon the shaft 72. A pinion 79 preferably formed integral with the gear 78 meshes with a gear 80 keyed to the shaft 75. Obviously, the gears and pinions 73, 74, 76, 78, 79 and 80 constitute speed reducing mechanism, the construction bein such that the shaft 72 drives the shaft 75 through the speed reducing mechanism.

It will be readily understood that if the lever or handle 66 is displaced to bring the clutch members 57 into effective engagement with the clutch member 56, the pinion 47 will drive the gear 48 and the shaft 46, which shaft will drive the shaft 72 through the sprocket chain 69. The rotation of the shaft 72 is of course imparted to the shaft 75 to drive the wheels 32, and the truck will be advanced towards the truck unit 21.

If the lever or handle 66 is manipulated to bring the clutch member 55 into effective engagement with the clutch member 53, the shaft 46 will be driven through the sprocket chain 44 and the rotation of the shaft 46 will be imparted to the shaft 75 through the mechanism above described. However, in this instance, the wheels 32 will be Irotated to displace the truck unit 20 to the left (Fig. 1)

The shaft 36 constitutes'a part of speed changing mechanism which is identified generally by reference character controlled by a hand-wheel 91 accessible to the operr ator (see Fig. 5). The details of the speedchanging mechanism 90 do not-form a part of this invention as any other suitable speedchanging mechanism may be employed, if it is desired. By means of the speed-changing mechanism 90, various speeds will be imparted to a shaft 94 jourhaled in the frame 30 and provided with a sprocket .95 which drives va sprocket 96 through the medium of a sprocket chain 97, the sprocket 96 being fixed to a shaft 99 journaled in the frame 30. A pinion 100 fixed to theshaft 99 meshes with a gear 101 fixed to a shaft 102 and a worm 103 fixed to the shaft 102 meshes with a wormgear 104 j ournaled upon a tubular shaft 106. Formed integral with the worm-gear 104 are clutch jaws 108 engageable with clutch jaws 109 provided upon a clutch member 110 splined to the tubular shaft 106. Riding in gee a groove 112 formed in the clutch member y 110 is a clutch collar 114'having pins 115 `engaged with the bifurcated .end of a lever 116. The lever 116 is pivoted to the frame 30 by a pin 117 and is connected by a link 118 to a lever 119 pivoted to the vframe 30 by olperator and may be manipulated to bring i jaws 108, the tu '130 the hub .bein

clutch-jaws 109 into and out of engagement with. the clutch-jaws 108. Obviously, when the clutch-'aws 109 engage the clutch-v ular shaft 106 will be ro-l tated.

The tubular shaft 106 is rotatably jour-l naled in bearin 125, 126, provided upon the frame30. Re erring to Fig. 6, it will be noted that a tube 128 is concentrically dis-.-

posed within the tubular shaft 106 andl is secured in place by a sleeve 129 and a hub referably formed integral with a disc 131. le construction is such that when the shaft 106 is rotated, the shaft 128, the sleeve 129 and the disc 130 will alsov rotate. Screw-threaded u on the peripheryof the disc is any annular ange 133 preferably formed integral with acylindrical head 134 which hasl its front endclosed by an integral Awall 135. The chamber within. the head 134 located near the periphery'of the disk 13.8.

The flange 133 forms an annular shoulderl 141 upon the head 134 and seated against this shoulder is a ring 142. Abutting the ring 142 and snugly-fitting the external cylindrical surface of the head' 134 is a sleeve 143, and abutting the sleevel 143 and snugly 'fitting the external cylindrical surface of the head 134 is a sleeve 145 which is preferably formed from copper. It will be noted that the thicku ness of the wall of the sleeve 145 is less than that of the sleeve 143 so lthat an annular shoulder 147 is provided.

c During the operation of the improved ap-l' and t e construction is preferably such that when the tubular end-piece 11 'abuts the an- 1 nular shoulder147, the adjacent end ofthe spiral pipe 1'0 overlaps a portion of the copper sleeve 145.

Mounted on a post 148 preferably formed integral with the wall is a collar 149 of a diameter substantially equal to the external diameter of the coppxer sleeve and the internal diameter of t `e spiral pipe 10. A tapered yportion 150 formed upon the col lar 149 functions as'a guide when'the end 11 and the pipe 10 are being positioned upon the head 134. l The collar 149 is rigidly secured to the head 134`by' a nut 153 screwthreaded upon the post148..

Projecting from the left-hand' end (Fig. 6) of the tube 128 and/rigidly secured thereto is a sleeve which has its outer end closed by a nut 156 screw-threaded thereonl `Car ried bythe nut 156 and by a bushing 158 mounted in the sleeve 155 isa tube 160 which X the chamber 136. That end ofv the tube 160 which is secured in the nut 156 ,is closed by a plug 162. Intermediate the nut 156 and the bushing 158 the tube, 160 is, provided with one or more apertures 164 in its Wall.

Thesleeve 155 is provided with an aperture 167 positioned to one side of the bushing 158 and with an aperture 168 disposed on the other side of the bushing 158.` yRotatably journaled upon the sleeve 155 are collars 170 and 171 and screw-threaded into the collars and 171 are pipes 17 3 and 174, respectively, whereby cooling fiuid may be circulated through the head 134. Thus the cool- .to discharge the cooling fluid into the chamber 136. The cooling fluid returns to the 'pipe 174 by way of the aperture 140, the bore of the tube 128, the bore of the sleeve 155. and the aperture 168 provided in the sleeve 155. Obviously, the pipes 173 and 174 may be connected to any supply of cooling fluid, and it is also `obvious that they will hold the collars v170 and 171 stationary. For this reason, I provide a plurality of packings 180, 181 and 182 for preventing leaks.' v

Screw-threaded into the frame 30 is a tubularpost 185 upon which a Welding device is adjustably mounted. The welding device y186 ispreferably of the metallic electrode type and is of well known construction.

Briefly, it comprises means for automatically. feeding a welding wire 188 to thearc and automatic means for maintaining an arc length and a constant arc voltage. The wire 188 vis drawn from the `spool 189 mounted at the upper end of the tubular post 185. The construction is such that when the tubular member 11 at the left-hand end of the pipe 10 (Fig. 1) has been properly positioned upon the hollow head 134, the head may be rotated and the welding device.y 186 may be ,set in operation to weld the tubular member 11 to the pipe 10, as indicated'l at 2190 in Fig. 6. Pivoted by a pin 193 to the frame 30 is a dog 197 which is provided with a jaw 1 98 engageable with the tubular member'll when the dog is displaced in a-counter-clockwise direction (Fig. 2) from the position where it is shown in Fig. 6.l The means for displacing t-he dog 197 in a counter-clockwise direction preferably comprises a lever 200 formed integral'with a pin 201 j ournaled in the frame 30, the lever 200 beingpivoted intermediatey its ends and having one` end engagea-ble with the dog 197. The purpose of this construction will presently appear.

.The truckunit 21 comprises a frame 30a which is referably substantially identical with the a ove described tframe 30 with the exception thatpreferably no provision is made therein for jurnalingshafting of the kind provided in the frame 30 for rotating a hollow head 134a and'displacing the truck unit 21 relative to the truck unit 20 (see Figs. 1 and 7).` However, the frame 30@ preferably comprises bearings 125@ and 126@ which journal a tubular shaft 106@ which is identical in construction with the above described tubular shaft 106, and carries like parts, including-sleeves 143@ and 145@ which are identical to the above described sleeves 143 and 145, the sleeves 143@ and 145@ forming an annular shoulder 147 which serves as a stop for the tubular member 12. lt will be noted that the tubular shaft 106@ is provided with a hollow head 134@ identical to the above described head 134 and that the hollow head 134@ carries a tapered member 150@ having the same func-I tion as the member 150. Also means identical with theV means shown in Fig. 6 is provided for circulating a cooling fluid through the hollow head 134@.

Screw-threaded into the frame 30al is a tubular post 185@ which carries a welding device 186@ preferably identical in construction with the welding device 186and supplied with a welding wire or electrode 188@ from a spool 189er, carried by the post 185@. lt will be noted that the frame 30a is provided with a dog 197@ and a lever 200@ which are identical to the dog 197 and the lever 200, respectively" and have the same functions, the dog 19T@ being provided with a. jaw 198e.

The operation of the above described ap paratus is substantially as follows: Assum` ing that the pipe 10 and the tubular mem` bers 11 and 12 are not positioned between the truclt units 20and 21 and that 'the truck unit 20 has been displaced in a direction away from the truck unit 21, it is readily understood that the sleeve 11 may be slipped in place upon the hollow head 134 and that the sleeve 12 may be set in place upon the hollow head 134@. rEhe pipe 10 may then be rolled along the ways 28 and 29 into a position wherein its longitudinal axis is disposed substantially in the same vertical plane as the co-incident axes of the tubular shafts 106 and 106e. The operator may then manipulate the lever 66 to advance the truck unit 20 toward the truck unit 21 whereupon the tapered end 150 of the collar 149 will enter the left hand end (Fig. 1) of the pipe 10 and the tapered end 150@ of the collar 149a will enter the right hand end of the pipe 10. lt is readily understood that if the operator continues to advance the truck unit 20 towards the truck unit 21 the 'tapered ends projecting into the pipe 10 will lift the pipe and bring it into a position wherein it is concentrically disposed with re` spect to the heads 134 and 134@ and con` tinued displacement of the truck unit 20 will cause the ends of the pipe 10 to abutthe edges of the tubular members 11 and 12. The lever 66 is then brought into its neutral position and the lever 119 is manipulated so` that it causes the clutch jaws 109 to engage the jaws 108 whereupon the tubular shaft 106 is rotated, and this rotation is transmitted through the pipe and through the tubular shaft 106@. As soon as the pipe 10 and the i tubular members 11 and 12 have commenced pipe 10 are no longer rotated. The lever 66 is then manipulated to withdraw the truck unit 20 suliciently so that the hollow heads 134 and 134@ and the collars '149 and `14911 will be withdrawn from the pipe and from 4 the tubular members 11 and 12, whereupon the pipe'drops down upon the ways 28 and 29 and may be rolled away to make place for the following pipe.

1n the event the pipe 10 or the tubular members 11 and 12 adhere to the hollow heads 134 and 134@, or to the collars 149 and 1490:, the lever 200@ associated with the frame 30a may be manipulated to bring the jaws 1980: int-o engagement with the inner side edge oi the tubular member 12, whereupon the tubular member 12, together with the pipe 10 and the'tubular member 11 will be held in a tixed position with respect to the trucli unit 21, then if the lever 66 is properly manipulated the truck unit 20 will back awa-y from the truck unit 21 and forcibly withdraw the head 134 and the collar 150 from the tubular member 11. Then to dithdraw the tubular member 12 from the head 134a, the same method may be employed by bringing the jaw 198 into engagement with the inner side edge oi the tubular member 11`after the head 134 has been re-inserted in it, then if the truck unit 2 is backed away, thetubular member 12 will be pulled off of the head 134@ after which the jaws 198 may be disengaged from the tubular member 11 and the truck unit 20 may be backed away a further distance so that the pipe 10 will drop upon the ways.
